OptoTest OP930 Insertion and Return Loss Test Set

Insertion loss (IL) and return loss (RL) on fiber optical components are measured fast and accurately with the OP930. The return loss is measured with the "no mandrel" method, meaning neither matching gel nor mandrel wraps are required at the far end of the cable. The insertion loss is measured by utilizing the stable transmitter of the return-loss as the source in combination with the precision optical power meter.
Like other OptoTest equipment the OP930 supports the USB interface. The OPL-PRO turnkey application software fully integrates this instrument into the data acquisition process of the high efficient production line.
